Terms of Service

These terms govern your use of OpenFeeCalculator, a public website operated by Alex Builds Studio. By using the site, you agree to them. If you do not agree, do not use the site. The calculators provide estimates only; they are not official statements, tax advice, legal advice or financial advice.

The service

OpenFeeCalculator publishes bilingual, static pages and client-side tools that apply documented marketplace fee schedules. You may use the free calculators without an account. We may change, pause or remove features. We do not guarantee uninterrupted availability, and we do not guarantee that a rate is still current the hour after an official page changes. The methodology and changelog explain how rates are sourced and dated.

No paid plan

OpenFeeCalculator is free to use. There is no subscription, no checkout, and no paid unlock. Every calculator, the full comparison grid, reverse pricing, batch mode and share or save tools are available without an account. If that ever changes, these terms and the privacy policy will be updated on the same day.

Acceptable use and intellectual property

You may not misuse the site, attempt to disrupt it, scrape it in a way that degrades service for others, or present the estimates as official invoices from a marketplace. The site's original text, layout, code and brand mark are owned by Alex Builds Studio except for third-party trademarks and open-source components, which remain subject to their own licenses. Marketplace names are used only to identify fee schedules, as described on the about and disclaimer pages.

Limitation of liability

To the fullest extent permitted by law, Alex Builds Studio is not liable for lost profits, lost listings, tax filings, or other damages arising from your use of an estimate or from a period of downtime. Your sole remedy for dissatisfaction is to stop using the site. These terms are intended to be read with the privacy policy and the disclaimer. The governing language for interpretation of the English and Chinese versions is that both are official; if they ever conflict, email us and we will correct the text.
